they are what you call when there are two tide cycles in one day--when there is only one tide cycle in one day that is called diurnal--diurnal tides occur in the Gulf of Mexico.
That depends on what you're relating the spin to. If the Earth did not spin relative to space itself, there would be a diurnal cycle. However, each 'day' would last half a year, with the other half occupied by one night. If the Earth did rotate, but did not rotate relative to the Sun, we would be in much the same situation the Moon is in with us - one face always showing to the Sun, the other always hidden. In this scenario, we would have no diurnal cycle.
semidiurnal tides are when there are two tide cycles in one day, and that is the common tides. diurnal tides are when there is only one tide cycle in one day, like in the Gulf of Mexico.
During the diurnal cycle the Earth has completed one rotation which takes 24 hours. The diurnal cycle refers to any pattern that repeats itself every 24 hour.
Diurnal cycle
== 1. (biology) belonging to or active during the day; "diurnal animals are active during the day"; "diurnal flowers are open during the day and closed at night". 2. Having a daily cycle or occurring every day; "diurnal rhythms"; "diurnal rotation of the heavens"; "the diurnal slumber of bats".
An antonym to diurnal is nocturnal when diurnal is defined; of or belonging to or active during the day; "diurnal animals are active during the day"; "diurnal flowers are open during the day and closed at night" Another antonym to diurnal is aperiodic (vs. periodic) when diurnal is defined; having a daily cycle or occurring every day; "diurnal rotation of the heavens" ~gpack

Killer whales are diurnal. They are most active during the day time, with each Pod having its own unique daily cycle/routine.

Giraffes are are diurnal
